Reiner Lemoine Institut

About us
Reiner Lemoine Institute is an independent non-profit research institution that contributes to a transformation towards a sustainable energy supply based on 100 % renewable energy. Our three research fields are “Transformation of Energy Systems”, “Mobility with Renewable Energy”, and “Off-Grid Systems”. We conduct applied research to scientifically support the long-term transition of the energy supply system towards renewable energy.

Our three research fields are:

Transformation of Energy Systems | We model, analyze, and optimize energy systems with a high share of renewable sources of energy. In doing so, we largely rely on open-source tools, which we develop ourselves.

Mobility with Renewable Energy | As a contribution to the German Energy Transition in the transport sector, we examine how alternatives to gasoline and diesel engines – such as battery and fuel cell powered vehicles or synthetic fuel – can be incorporated in renewable energy systems in an economically and ecologically reasonable manner and what kind of charging infrastructure will be needed in the future.

Off-Grid Systems | We support the Seventh UN Sustainable Development Goal (SDG7) with a special focus on access to energy in remote regions and on islands. Our approach is to apply geoinformation software, socio-economic analyses, and energy system modeling in order to compare different options, such as grid extension plans, mini-grids, and solar home systems.

The Reiner Lemoine Institute was founded in 2010 by the Reiner Lemoine Foundation, which supports the Institute financially, though we raise 90 percent of our research funding from external sources. These consist largely of state, national, and European funding means as well as research contracts and consulting in the public sector, non-governmental organizations, and the private sector.

Guiding Principle
We are committed to the philosophy of our founder Reiner Lemoine. His vision was of a livable future for all people, and with our work we aim to contribute to a successful Energy Transition. The Energy Transition shall be shaped and funded through the participation of all citizens and thus contribute to a fairer society. Our research results and findings are validated under real-world conditions wherever possible and made available to the public. We work self-critically, transparently, and are committed to scientific research ethics. In our research practice, participatory collaboration and a trustful and respectful work environment is important to us.

Reiner Lemoine
Reiner Lemoine was born in 1949 in Berlin. He studied aerospace engineering and graduated from the Technical University of Berlin in 1979. Reiner Lemoine is considered as one of the main pioneers in the field of renewable energy in Germany. Together with friends and business partners, he founded a number of innovative companies, such as Wuseltronik GbR, an engineering office for measuring technologies and renewable energy technology in 1978, the Solon AG in 1996, and Q-Cells AG, a developer and manufacturer of high-performance solar cells in 1999.

As a visionary and advocate of the Energy Transition, Reiner Lemoine contributed with perseverance and exceptional willingness to take risks to the establishment of renewable sources of energy in our society, transforming these from a “niche” technology into a rapidly growing industry with world-wide renown for the long-term economic and developmental benefit of humanity. Although Reiner Lemoine focused on technical aspects of renewable energy, he kept social and political aspects in mind: Renewable energy strengthens the independence of nations, reduces conflicts over fossil fuels, secures the livelihood of millions of people and protects the environment. His commitment was deeply ethically motivated. This is illustrated in the way he managed his companies: For example, he founded the Wuseltronik GbR as a "collective" with equal remuneration for all employees and joint decision-making. Even in later and larger companies, a positive work environment for all employees was one of his priorities.

After Reiner Lemoine passed away in 2006, the Reiner Lemoine Foundation continues the legacy of its namesake and founded the Reiner Lemoine Institute in 2006.
